CULTIVATO R.

SPECIFICATION forming partiof Letters Patent No. 288,514,` dated November 1.3, 1883- I Application filed July Eames. (Ndmodel.)

.T0 all whom t may concern Be it known that I, HENRY V. THOMPSON, a citizen of the United States, and a resident of Bushton, in the county ofColes and State of Illinois, have invented certain new and useful Improvements in Corn-Cultivators; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to 'make' and use the same, reference being had to the accompanying drawings, whichform a part of this speciiication, and in which- Figure l is a front or face view of my improved corn-scraper attachment for cultiva- Fig. la is a side view of the same. Fig. 2 is a vertical cross-section thereof. Fig. 3 is a view of the several details of the clamp for connecting the scraper to aplain-faced standard ofthe cultivator; and Fig. 4 is a detail view of one of the clamps, showing it adapted for standards with rounded or conveXed surfaces.

This invention has relation to an improvement in scraper-s lor corn-cultivators; and it consists ofthe combination and arrangement of parts, substantially as hereinafter fully set forth.

In carrying out my invention I employ a right and aV left scraper, only one, A, being shown, which is adapted to take the place of the ordinary shovel used to scrape the earth around corn in cultivating the same.

The characteristic features of my invention deal more especially with the means employed to connect the scraper or Scrapers to the standards; and to this end I provide the scrapers each, near its upper edge and on the rear side, with sockets a, one arranged near each end. The sockets a are provided with inwardlyprojecting iianges at their outer edges, and arranged horizontally.

b b are blocks or slides, recessed on their inner sides to enable them to receive the projecting sockets a of the Scrapers, over which they slide horizontally. Through these blocks or slides pass screw-bolts c, which also pass through the cultivator-standards B, and thus effect the connection of the scrapers to the latter, said bolts having heads beveled on the under side, which fit in the sockets a, under their anges, while nuts d are applied to their outer ends. Theouter surface of one or both of these blocks may be plain or concaved, to adapt the same to either angular or rounded cultivator-standards for the attachment of the Scrapers to the cultivator.

I am aware that Letters Patent No. 264, 885 have been granted to K. Kellogg for a plow in which the mold-board is secured to the body of the plow by means of bolts having flaring heads fitting into flanged sides cast upon the inside of the mold-board; butthe shovel-blade or scraper being :made of hammered or rolled plate metal, which precludes the possibility of forming the flanged sides integral with the blade, it is necessary to make the flanged slides -or sockets separately andatta'ch them by bolts `or similar means to the blade. I do not therefore wish to claim, broadly, the construction shown in the aforesaid patent; but

What I claim, and desire to secure by Letters Patent of the United States, is-

1 The combination of the cultivator-standards, the blocks having stepped recesses in their outer faces, the bolts having flaring heads, and inserted through the blocks and standards, the sockets or slides having inwardly-projecting flanges, and the scraper or shovel-blade having the said sockets or slides fastened upon its inner side, as and for the `purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

HENRY V. THOMPSON.
